Yes, my "fitness" foundation was built on it. Cardio came later, running came much later.

The reason I ask is because you look like you're in great shape but not necessarily a lifter.

My observation is that most men who lift become disproportionately large in the upper body. You, on the other hand, look very well proportioned.

One of my "problems" with the movie "Ali" was that it was obvious that Will Smith lifted weights to get in shape. He has that "top heavy" look with big shoulders and chest. Ali never looked like that - he was extremely fit and strong but didn't lift weights. Your build reminds me of Ali or some of the older fighters.
